Tapered Roller Bearings SKF 30206

The SKF 30206 tapered roller bearing, with main dimensions of 30 × 62 × 17.25 mm, is designed to accommodate high radial forces and single-direction axial loads in mechanical engineering applications.

The 30206 tapered roller bearing belongs to the group of radial roller bearings and is characterised by its tapered rollers and raceways. This design results in line contact between the rollers and raceways, enabling the bearing to accommodate combined radial and axial loads. This product is a complete roller bearing from SKF in the Explorer series. With a bore of 30 mm, an outer diameter of 62 mm and a width of 17.25 mm, the unit is suitable for demanding rotational movements in gearboxes and drive units.

What is the 30206 tapered roller bearing suitable for?

It is primarily used in designs where radial forces and axial forces occur simultaneously in one direction. Typical applications include gearbox shafts, wheel bearings and industrial drive systems. As single-row tapered roller bearings, by their design, can only accommodate axial forces in one direction, designers usually fit a second bearing in a mirror-image configuration opposite the first. This paired arrangement ensures a play-free or preloaded guidance of the shaft under varying load directions.

What are the key considerations when fitting and selecting the 30206 tapered roller bearing?

Tapered roller bearings are separable: the inner ring, with the roller set in a sheet steel cage, can be fitted separately from the outer ring. This facilitates installation in the housing and onto the shaft. When selecting the bearing, the permissible temperature range of –30 to +120 degrees Celsius must be taken into account. The bearings are manufactured to tolerance class P0/PN (corresponding to ABEC 1). During installation, the operating clearance or preload is adjusted using shaft nuts or shims to suit the thermal behaviour of the bearing assembly.
